Q:How to inspect ductile iron pipe fittings?

The quality of water supply pipe ductile is a topic worthy of discussion, how to judge the quality of the ductile iron pipe, ductile now on the market is all kinds of pipe, a name sand type ductile iron pipe, ductile water-cooling tube, K8 grade K9 grade ductile iron pipe, ductile iron pipe, also the brand is divided into ductile ductile pipe pipe, big brands, and some well-known manufacturers of producing ductile pipe

Q:Is the ductile iron pipe metal pipe?

Ductile iron pipes are metal tubes, because ductile iron is also a kind of metal. See the classification of metalsGenerally, metal materials are classified into two major categories: ferrous and non-ferrous metals

Q:Could you tell me how to weld ductile iron parts and steel tubes?

Disk or disk plug connection, it is best to use flange connection. First insert a flange plate on the ductile iron pipe and then screw it with the flange on the weld pipe. But note, because ductile iron pipe material is crisp, and the two connecting flange sealing surface is best all the plane, in order to prevent damage due to uneven iron flange.Material is different, ductile iron pipe is made of ductile iron, seamless steel pipe is made of structural steel. Such as No. 20 steel, No. 35 steel, 16Mn steel and so on. The two is the manufacturing process is also different, ductile iron pipe is generally sand casting molding; seamless steel pipe is made of billet through seamless steel tube mill hot rolling molding.

Q:How is the weight of nodular cast iron pipe calculated?

The use of cast iron by adding more than 18 nodularizer, after centrifugal ductile cast iron machine high speed centrifugal cast pipe, called "ductile" (Ductile Cast Iron Pipes), referred to as ball pipe, ductile iron pipe and ductile iron pipe etc.. The utility model is mainly used for conveying water, and is an ideal choice for tap water pipes.

Q:How can ductile iron pipes be connected to steel tubes?

First insert a flange plate on the ductile iron pipe and then screw it with the flange on the weld pipe.

Q:How much is the installation of a two degree elbow for ductile iron pipe fittings at 11.25 degrees?

Using more than 18 cast iron, after adding the spheroidizing agent, the centrifugal casting of ductile iron machine caused by high-speed centrifugal tube, known as "ductile iron pipe."".

Q:What are the categories of ductile iron pipe fittings?

The heat pipe trench is in rotational groove tube internal high temperature composite cold water general PE, cohesive force is very strong and do the destructive test will be found with a knife, the pipe made by hot plastic process, lined with PE layer inside the hard to cut down. The injection pipe is a kind of composite pipe formed by injection of PP into the inner part of the groove pipe.

Q:How can the ductile iron pipe be connected to the PE pipe?

Through the conversion of fittings, because different PE pipes and ductile pipe diameter pipe, so name is needed for the step coupling, called Chinese stepped rod joints

Q:How to improve the quality of nodular cast iron pipe fittings

When the molten iron temperature is too low and the inner wall temperature of the tube is low, heavy skin defects will occur. When the molten iron temperature is high and the molten iron gas increases, porosity defects can be generated. In the medium frequency furnace, the hot metal should be provided according to the process specification, and the temperature of the inlet and outlet and the cooling rate can be controlled reasonably in the process of production.
